sftp and escape characters

[ross]

Recently, I wanted to upload a file to my friend using sftp. The problem  
is that the file had a space in the file name and the standard escape  
character of \ didn't seem to work. Is there a way around this? Am I crazy  
and doing it wrong? for reference, the line I entered in the sftp prompt is

sftp> put /mnt/pammy/music/Nadasurf-\ Popular.mp3 /files/upload
File "/mnt/pammy/music/Nadasurf-\\" not found.

Thanks
